“…Yes. Several papers in the present issue illustrate nicely that there is an established scientific basis for drawing conclusions on a number of topics, such as the confidence-accuracy relation (Brewer & Weber, 2008;Deffenbacher, 2008), decision latency (Brewer & Weber, 2008), stress (Deffenbacher, 2008;Memon et al, 2008), the retention interval (Deffenbacher, 2008), and lineup composition and instructions (Clark, 2008). This is not to suggest that the book is necessarily 'closed' on these topics; research areas continually evolve as new questions arise, new methods are developed, and so forth (Malpass et al, 2008).…”
